Question

What will happen to the instruction latency as a result of introducing the pipeline? A. The latency will remain unchanged. B. The latency will decrease from 6 cycles to one cycle as a result of using the pipeline. C. The latency will increase from one cycle to 6 cycles as a result of using the pipeline. D. The latency will depend on the opcode of the instruction. E. The latency will depend on the throughput.

Answer 1

Answer: C.

. The latency will increase from one cycle to 6 cycles as a result of using the pipeline.

Explanation: Pipelines are serially connected sets of instructions where the output of one becomes the input of the next.

Pipelines usually consists of several stages of which the slowest stage is the determines the clock cycle time.

Pipelines usually uses some times to register it clocks

Pipeline clocks are usually routed to separate registers which adds delays to the system.

Clock time is affected by the clock skey( arrival of a sourced clocked at different times within the cycle)signals at and the routing times.
